While it’s said that opposites attract, particle physicists are taking no chances. In hopes of learning what the universe is made of, they’re preparing to build a machine that will accelerate and smash together electrons and their opposites, positrons, 14,000 times every second. Like Jefferson Lab’s Continuous Electron Beam Accelerator Facility (CEBAF), the proposed new […]
Cornell University Moves Forward on Vertical Electropolishing
Recent results from Cornell University demonstrated that a new method of electropolishing superconducting cavities may hold promise for the International Linear Collider. For the past two years, Cornell scientists have been developing an electropolishing method that treats cavities vertically as opposed to the traditional horizontal orientation developed by KEK. Cornell recently applied this new vertical […]
Above 42 MV/m for a single cell cavity electropolished at Saclay
Last January, engineers from the DAPNIA laboratory in Saclay France qualified a new electropolishing facility for single cell cavities. Their first electropolished cavity reaches a promising result, above 42 MV/m (megavolts per metre) of accelerating gradient. It allows them to join the global R&D effort on these cavity treatments. The newly qualified electropolishing facility at […]
From symmetry Magazine: Evolution of a Collider
As physicists and engineers devise ways to make the International Linear Collider perform better at a lower cost, the design evolves, sometimes with tweaks but at other times with major reconfigurations. Photo: Reidar Hahn, Fermilab Designing the International Linear Collider is an evolutionary process. The ILC would be a next-generation machine that smashes together electrons […]
U.S. Congressmen Address ILC R&D and Industrialisation
Last week on 28 February, U.S. industry members and scientists gathered at the Linear Collider Forum of America meeting on Capitol Hill in Washington, D.C. to start a dialogue with congressmen and senate and house staffers about the International Linear Collider. The recent publication of the Reference Design Report made the meeting a timely venue […]
Testing, Testing
A brand-new test stand at DESY puts complete modules under the test. The performance of the module, its cavities, couplers and cables can be examined in great detail. Module 6 has had a bit of a break since we last reported on its progress (NewsLine 11 May 2006 and NewsLine 15 June 2006). It spent […]
STF – Getting ready for the experience
An important prerequisite for building the ILC is to establish the design and manufacturing of major and vital components, such as cryomodules for the main linacs through realistic operating conditions. The Tesla Test Facility (FLASH) at DESY and Fermilab’s ILC Test Area have been pursued to play critical roles in the European and American regions […]
Electron Cloud Studies Conducted at Cornell University
In the end of January, the Laboratory for Elementary Particle Physics (LEPP) at Cornell University hosted collaborators from KEK, Lawrence Livermore National Laboratory, Argonne National Laboratory and Alfred University (an undergraduate University in New York State) to conduct electron cloud studies using the CESR storage ring. CESR is unique in that it is a “wiggler […]
Japanese Diet Members started a workshop on ILC
On June 15 last year, the Japanese “Federation of Diet members to promote the realisation of ILC” was formed (See NewsLine from 22 June 2006). The Diet members of the federation held a workshop with ILC researchers on 22 January 2007 in Nagatacho near Tokyo. Nobel laureate Masatoshi Koshiba and Professor Kazuo Nishimura (Kyoto University), […]
From SLAC Today: ILC Physics: The Analysis Has Already Begun
For the proposed International Linear Collider, physicists are trying to both design the most precise calorimeter ever and still be able to afford it. A calorimeter measures the energy of particles in a detector, and is typically the single most expensive part. If you reduce its performance slightly to reduce costs, how much have you […]
